Abstract
Description
以下、本発明の理解を助けるために好適な実施例を提示するが、下記の実施例は本発明を例示するものであるだけ、本発明の範疇及び技術思想の範囲内で多様な変更及び修正が可能であるのは当業者に明らかであり、このような変形及び修正が添付の特許請求範囲に属することは言うまでもない。
ドネペジル塩酸塩を10mgの含量で含むEisai Korea社のアリセプト10mgを使った。
メマンチン塩酸塩を10mgの含量で含むLundbeck Korea社のエビキサ20mg(10mg×2)を使った。
ドネペジル塩酸塩一水化物41.72g(10.4mg)、マンニトル480g(120mg)、ヒドロキシプロピルメチルセルロース20g(5mg)を混合する。これとは別に、精製水120gにヒドロキシプロピルセルロース20g(5mg)を添加して溶解させた後、前記ドネペジル塩酸塩混合物に添加し、スピードミキサーで混合させた後、前記混合物を60℃で2時間乾燥し、オシレーター20meshで濾過して定粒(d(0.1)9.6μm、d(0.5)141.8μm、d(0.9)784.3μm)する。
前記実施例1と同様な方法で実施するが、混合物をオシレーター16meshで濾過して定粒してドネペジル定粒物を収得して用いた。
前記実施例1と同様な方法で実施するが、混合物をオシレーター25meshで濾過して定粒してドネペジル定粒物を収得して用いた。
前記実施例1と同様な方法で実施するが、混合物をオシレーター30meshで濾過して定粒してドネペジル定粒物を収得して用いた。
前記実施例1と同様な方法で濾過されたドネペジル定粒物を製造する。
実施例1と同様な物質及び含量を使った。
実施例1と同様な物質及び含量を使った。
ドネペジル塩酸塩一水化物41.72g、マンニトル480g、ヒドロキシプロピルメチルセルロース20g、メマンチン80g、ヒドロキシプロピルセルロース20g、SD乳糖492g、Vivapur12 48gを20meshで濾過して混合した後、ステアリン酸マグネシウム16gを追加的に添加して混合した。その後、前記ドネペジルとメマンチンが混合された混合物をロータリー打錠機で圧縮して打錠した後、オパドライ40gコーティング基剤を用いてフィルムコーティングした。
試験例1.溶出試験
対照群1及び2と実施例1で製造された複合錠剤に対して下記の条件で溶出試験を実施した。
対照群1:対照群1(アリセプト10mg)単一溶出
対照群2:対照群2(エビキサ10mg×2錠)単一溶出
対照群1、2:対照群1(アリセプト10mg)及び対照群2(エビキサ10mg×2錠)を単純混合して同時複合溶出
実施例1:複合錠剤
実施例及び比較例で製造された複合錠剤を40及び75%相対湿度でアルミニウム(Alu−Alu)包装を適用して加速安全性試験を実施し、2週ごとに気体クロマトグラフィー法で時間による総不純物質含量(%)を分析した。
含量均一性測定は試験例1の溶出試験の分析法と同一であり、試験は大韓民国薬典一般試験法の製剤均一性試験法によって試験した。製剤均一性試験法は各製剤間の主成分含量の均一な程度を示すための試験法である。
判定値=M−平均含量+(2.4×標準偏差)
